BACKGROUND AND OBJECTIVES The redox system is an important anti-oxidative system composed of thioredoxin, thioredoxin reductase, and peroxiredoxin (PRx). The fine details of PRx expression and its protective effects in various cells in cardiovascular tissue under oxidative stress created by hydrogen peroxide have not been fully elucidated. SUBJECTS AND METHODS Oxidative stress was induced by ...

in concentration of hydrogen peroxide, first, the solution should be quite pure, and then, it concentrate with methods such as vacuum distillation and cooling crystallization, because impurities in the hydrogen peroxide solution in high concentrations are causing decomposition of this substance; that is very dangerous. the purpose of this article is separation of chromium and magnesium cations ...

It has been proposed that the mutagenic activity associated with the ascorbic acid autoxidation system may involve hydrogen peroxide and peroxide radicals. We report here that the system may involve hydrogen peroxide and peroxide radicals. We report there that the mutagenic effect may also partially reside in as yet unknown secondary products. The observed mutagenicity of 2,3-diketogulonic acid...

introduction: the present study evaluated the element distribution in completely set calcium-enriched mixture (cem) cement after application of 35% carbamide peroxide, 40% hydrogen peroxide and sodium perborate as commercial bleaching agents using an energy-dispersive x-ray microanalysis (edx) system. the surface structure was also observed using the scanning electron microscope (sem). methods ...

The irreversible inhibition of catalase by 3-amino-l, 2,4-trizole and a group of related inhibitors (1) in the presence of a continuous supply of hydrogen peroxide has been shown to result from a reaction of the inhibitors with catalase-hydrogen peroxide complex I (2) in which 1 mole of inhibitor is incorporated into the enzyme protein for each mole of catalase heme that has reacted (1). The ki...
